We have the same two beer event happen. Rifle company was on a very long bus trip cross-country. At a truck-stop they pass the word everybody could purchase two beers. Every damn Marine can strutting out carrying two 32 oz beers with a big smile. Company gunny almost popped a critical vessel, but then caught himself and said “damn it, this is my fault not yours. I failed to say two 12 oz beers”.
Knew a gunny like that once. He often made little “mistakes” that we’d benefit from. Once he made Top....he stopped with the mistakes.
Come on Top....
;)
We were the only rifle company returning to Okinawa in anyone's memory that didn't undergo a the mandatory Division's urinalysis after deployment to the Philippines. Word got back to the battalion and regimental HQ (through back channel) that they would lose an entire company, to include its officers and staff NCOs if we returned directly and were tested. So we were sent to Range Company, Mount Fuji, Japan for the winter to dry out and get the THC out of the blood stream.
At Fuji, we converted a quonset hut into a company all-ranks club and christened it with a toga party. But the drugs and various venereal diseases were dealt with.
So yeah, the culture runs deep, probably fueled from the horrors of Vietnam, Korea, and WWII.
